JOSEPH IV. PENBERTHY, OF MINNEAPOLIS, MINNESOTA.

DENTAL CABINET.

SPECIFICATION forming part of Letters Patent No. 386,492, dated July 24,1888.

Application filed February 14, 1988.

T 0 aZZ 107L077? it may concern.-

Be it known that I, JosEPH \V. PENBER- THY, of Minneapolis, in thecounty of Hennel pin and State of Minnesota, have invented an ImprovedDental Cabinet, of which the following is a specification.

The object of my invention is to provide a cabinet or case that isparticularly adapted for holding dental instruments,though applicablefor holding other articles.

The invention consists, generally, in a bracket, table, or cabinet, andone or more frames or slides arranged therein and provided with apivoted receptaclethatis adapted to be closed up into the frame and tobe shut up with it into the cabinet and to drop intoa vertical positionwhen the frame is drawn out of the cabinet.

In the drawings which form a part of this specification, Figure 1 is aperspective view of a bracket, table, or cabinet embodying my invention.Fig. 2 is a longitudinal section showing the drawers or frames closed.Fig. 3 is a cross-section through one of the drawers or frames.

In the drawings, 2 represents the cabinet or casing, which may be madeof any convenient size and may be provided with any number of drawers orframes 4, arranged to slide into said ease in the ordinary manner. Eachof the drawers or slides 4 is preferably pro yided with a movable plateor drop, 5, which is pivoted to the sides of the said slide and swingsfreely on its pivots. The pivots are so located that the predominenee ofweight will be on one side of them, preferably at the back, to cause theplate or drop to fall when the slide is pulled out and stand in aperpendicular position with the open ends of the compartments uppermost.

In order to protect the instruments and prevent them from beingdisplaced in closing or opening the slide, I prefer to form separatecompartments 6 in the pivoted plate or drop 5, which are made of anyrequired depth and and are open at the front, as shown in Fig. 2. A lipor shoulder, S, is preferably placed at the back of the pivoted plate ordrop 5, which strikes the frame or stationary part of the slide andlimits its upward movement, in order to Serial No.263.9l16. (No model.)

hold it in its proper position to allow the slide to be readily closedinto the cabinet.

Other instrument-holdcrs may be pivoted to the slide or drawer andconstructed substa tially similar to the one already described, and Ihave shown in the drawings one of the slides fitted up in this manner,in which case a partition or stop, 9, is placed at a suitable distancein front of this drop to prevent the instruments contained therein frombeing accidentally removed when the drawer or slide is opened or closed.

It will be seen that the upper plate or drop is pivoted in such a mannerthat when the lower drop is raised to close the drawerit will carry theupper plate with it and both will be closed into the slide.

In order to utilize the whole of the slide, I may make it double-endedand pass it through the cabinet and provide it with a till, 10. I do notconfine myselfto this construction,however,as asingle drawer can be usedif p referred. A drop may be placed in both ends of the drawer,ifpreferred, as shown in Fig. 2, in on der to give a greater number ofcompartments.

Suitable handles or knobs, 12, are usually provided for the slides.

The operation of the device is as follows: Each instrument is placed inits proper compartment, which is made of sufficient depth to allow thepoints to projectasuitable distance to allow for its being readilyremoved from the compartments. WVhen the instruments are in place, theplate or drop 5 is swung forward and upward until the shoulder 8 strikesthe bottom ofthe slide, when the slide can be closed. \Vhere two or moreslides are used in the same section, the lower one is first opened andthe drop allowed to take its perpendicular position. The next slideabove is then opened and the compartments or drop pivoted therein willswing upon their pivots, and the back ends of the said compartments willdrop through the open portion of the slide below,allowing them to standin a perpendicular position,as shown in Fig. l. The slides can then bepartially closed and bring the rows of instruments close to the edge ofthe cabinet and thus economize in room.

My invention is applicable for use not only to hold dental instruments,but For holding other articles, and the receptacles, instead of beingformed by plates having openings formed in them, may be constructed inany suitable manner.

I claim- 1. The combination, with the cabinet, of a drawer consisting ofa frame having sides and ends and an open bottom, and one or morereceptacles pi voted in said drawer and adapted, as the drawer is drawnout of the cabinet, to drop into a substantially perpendicular position,substantially as described.

2. The combination, with the frame or cabinet 2,0f a series ofrectangular drawers, 4,arranged to slide in said cabinet, provided withopen bottoms, plates or drops 5, pivoted to the said drawers andprovided with the series of compartments 6, and the shoulders or stops 8upon the lower plate or drop to limit its upward movement, substantiallyas described.

3. The combination, with the cabinet, of the drawer consisting of aframe having sides and ends and an open bottom, and a plate pivoted insaid frame and having a series of compartments formed in it andadapted,as the drawer is drawn out of thecabinet,to drop into asubstantially perpendicular position, substantially as described.

4c. The combination, with the cabiuet,of the slide arranged therein,andreceptactes pivoted one above another in said slide, with the pivots ofthe lower receptacle nearer to the front of the slide than those of theupper receptacle, substantially as described.

In testimony whereof I have hereunto set my hand this 10th day ofFebruary, 1888.

JOSEPH \Vt PENBERTHY.
